GEARING FOR WINDMILLS.

SPECIFICATION forming part of Letters Patent No. 345,317, dated July 13, 1886.

Application filed December 7, 1885. Serial No. 184,985. (No model.)

To all whom it may concern:

Be it known that I, GEORGE H.v Parrrrsou, a resident of Freeport, in the county of Stephenson and State of Illinois, have invented certain new and useful Improvements in Gearings for Windmills; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

My invention relates to improvements in gearings for windmills of the class known as power mills in contradistinction from pumping-mills.

The invention is fully described and explained in this specification, and shown in th accompanying drawings, in which Figure 1 is a central vertical section of the tower on which is mounted one form of the gearing constituting the subject of this application. Fig. 2 is a similar view of a modified form of the gearing; Fig. 3, a central vertical section of a tower provided with a third form of the gearing, and Fig. 4 a similar view of a fourth form of the gearing.

In Fig. 1, A are the posts of an ordinary windmill-tower, and D is a top plate fastened to the posts.

0 is a turn-table resting on the usual antifriction balls set on the top plate, D, and c is a horizontal wind-wheel shaft journaled in the turn-table and provided on its inner end with arigidly-mounted miter-gear, F. A hollow shaft, M, is journaled in suitable openings in the turn-table and top plate, and has on its lower end a rigidly-mounted spur-gear, 3, and on its upper end a rigidly-mounted mitergear, E, which engages with the miter-gear F on the wind-wheel shaft.

To the upper part or bridge-arm, O, of the turn-table O is fastened the upper end of a preferably hollow vertical shaft, X, which passes down through and extends a short distance below the hollow shaft M, already mentioned,

and on the lower end of the shaft X is rigidly gages with the spur-gear G, rigidly mounted on the shaft M, and the gear-wheel I engages with the spur-gear K, loosely mounted on the same shaft. A horizontal arm, N, carrying two vertical gudgeons, P, is rigidly connected with the gear K, and on each of the gudgeons I is mounted loosely a planet-gear, T, engaging with the spur-gear O, fastened to the shaft M, and also engaging with an internal gear, Q, rigidly fastened to the shaft M.

The operation of this system of gearing is as follows: If the turntable, with its shaft X and gear I, be held stationary, and the windwheel shaft and gear F be rotated in the direction indicated by the arrow on the gear, the hollow shaft M, together with its gears E 3, turns in the direction indicated by the, arrow on either of said gears, and consequently the gear G, shaft M, and gear 0 must turn in the opposite direction, as indicated by arrows on the gears. The turn-table, the Shaft X, and gear I being stationary, the gear K, arm N, and gudgcons l? are also stationary, and consequently the rotation of the gear 0 rotates the planet-gears T about the respective, gudgeons 1? without revolving them about the shaft M or about the axis of the gear 0. The rotation of the planet-gears T. rotates the internal gear, Q, in the direction indicated by the arrow thereon, and as the gear Q is rigidly fastened to the shaft M the shaft turns with the gear and transmits the motion of the mill to any mechanism to be operated. On the other hand, if the power-transmitting shaft M be held stationary and the turn-table be rotated in the direction indicated by the arrowv thereon, the shaft X and gear I turn inthe same direction, and the gear K, arm N, and gudgeons P turn in the opposite direction. The shaft M and internal gear, Q, being stationary, the rotation of the arm N rolls the planet-gears 'I about the internal gear, and thus rotates the gear 0 in the direction indicated by the arrow thereon. This rotation of the gear 0 is communicated through the shaft M and gears G to the hollow shaft M, which is thus made to rotate inthe same direction as the turn-table. The relative sizes of the gears are such as to give the shaft M and the turn-table the same speed of rotation, and thus the rotation of the turn-table, when the shaft M is at rest, turns the shaft M at a speed uniform with that of the turn-table itself, thereby preventing any rotation of the shaft ICO gear T is connected with the shaft M" through the spur-gear Q, which is fastened to the shaft, instead of through the internal gear, Q,.as in the form shown in Fig. 1, and the gear 0 is an internal gear instead of a spur-gear. The

only effect of this change is to vary the ratio of the speed of the shaft M to that of the shaftv c, the operation of the gearingsin all other respects being the same.

In'the form shown in Fig. 3 th'e gear K en-: gages with the gear 3, and the gear G engages with the gear I, which isa reversal of the order of connection of these gears in theform's-hown in-Fig. 1. Otherwise the forms 'shownin Figs. 1 and 3 are idenitcal.

The diflerence'between Figs. 3 and 4 is the same as that-between Figs. 1 and 2that is, the gear 0 in Fig. 3 is spur, and in Fig. 4 it is internal; and the gear Q is an internal gear in Fig. 3 while it is a spur-gear in Fig. 4. With this exception, Figs.- 3 and 4 are alike.

The bearing-r may evidently be supported from oneside only,instead of on both,'as shown.

In view-of mypatent May 5, 1885, I hereby disclaim for this invention any novelty, except such as is set forth in this specification and the following'claims.

Having now describedand explained my invention, what I claim as new, and desire to secure by Letters Patent, is-
